74AHCT240PW-Q100J

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT240PW-Q100J is an octal buffer and line driver with inverting logic and 3-state outputs, housed in a TSSOP20 (SOT360-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerant inputs that accept voltages higher than VCC. It supports TTL input levels and includes two independent output enable controls (1OE and 2OE). Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for extended temperature operation up to +125 °C
• Inverting octal buffer architecture with dual 3-state output enables allowing configuration as two 4-bit buffers or one 8-bit buffer
• Input compatibility with TTL logic levels and tolerance for input voltages exceeding the supply rail VCC

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring qualified logic components
• Mixed voltage environments utilizing overvoltage tolerant inputs
• High-speed data bus buffering applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the Q100 series includes SO20 and DHVQFN options alongside the PW TSSOP20. Confirm the grade designation aligns with automotive reliability requirements. Ensure the datasheet revision corresponds to the latest JEDEC ESD specifications before finalizing procurement documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with 3-state control is required for automotive designs. The AHCT series ensures direct interface with TTL-level signals while maintaining CMOS low-power characteristics. Verify that the TSSOP20 footprint fits the PCB layout constraints and that the thermal dissipation capabilities meet the application's power budget under maximum load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHCT240-Q100 family of octal buffers. Other variants in this family include the 74AHCT240D-Q100 in an SO20 package and the 74AHCT240BQ-Q100 in a DHVQFN20 package. All variants share identical electrical characteristics and functional descriptions but differ in physical packaging dimensions and thermal properties.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include the 74AHCT240D-Q100 and 74AHCT240BQ-Q100. These parts offer identical electrical performance but utilize different packages (SO20 and DHVQFN20 respectively). Physical footprint adaptation is required if replacing the PW variant with these alternatives.
